Estou tentando testar o uso das extensões sql do Saxon EE através do Oxygen. Estou recebendo um erro que o driver falhou ao carregar:

Nome do mecanismo: Saxon-EE 11.4
Gravidade: fatal
ID do problema: SXSQ0003
Descrição: Falha ao carregar o driver JDBC org.sqlite.JDBC
Local de início: 30:106
URL: http://www.saxonica.com/html/documentation/javadoc/ net/sf/saxon/trans/SaxonErrorCode.html#SXSQ0003

Este é o meu XSL:

Este é o arquivo de configuração SaxonEE em nosso projeto:

<configuration edition="EE" xmlns="http://saxon.sf.net/ns/configuration" label="Saxon-EE (no threads)">
    <global allowMultiThreading="false" 
        timing="true" 
        validationWarnings="true" 
        validationComments="true" 
        allowExternalFunctions="true" 
        compileWithTracing="false" 
        lineNumbering="true" 
        traceExternalFunctions="true" 
        expandAttributeDefaults="true" 
        allowSyntaxExtensions="true"/>
    <xslt>
        <extensionElement namespace="http://saxon.sf.net/sql" factory="net.sf.saxon.option.sql.SQLElementFactory"/>
    </xslt>
</configuration>

Tentei copiar o jar do driver SQLite mais recente (sqlite-jdbc-3.42.0.0.jar) para a pasta Oxygen lib e ele reclamou. Eu movi para a pasta lib/connectors. Ele não reclamou de estar localizado lá, mas ainda falha. Não tenho certeza de onde localizar o jar para que o Saxon carregue o JDBC.

Qualquer ajuda é muito apreciada.
